You can delete your Success Magis account yourself, from the website or from the Android app. Deletion is immediate and permanent: there is no waiting period and nothing is kept in a recoverable form.
Sign in, open your profile, and use "Delete my account" at the bottom of the page. You will be asked for your password to confirm.
Open the side menu, tap "View profile", then "Delete my account" at the bottom of the profile screen. The same confirmation applies.
Email successmagis@gmail.com from the address on the account and ask for it to be deleted. We will confirm once it is done.
